To all whom it may concern.:

Be it known that we, JOHN M. ,Pownizs and JOHN L. BOYD, citizens of the United States, and residents of St. Louis, Missouri,

have invented certain new and useful Improvements in Weather-Strips for Metal Frames and Sash, of which the following is a specification containing a full, clear, and exact description, reference being had to the .accomianying drawings, "forming a part hereo Our mventlon relates to a weather'strip for metal frames and sashes, and the object its of our invention is to provide a simple, inexpensive, and easily installed metal weather strip, which is particularly applicable for metal window frames and sashes, and which when ink use forms a practically air tight joint between the sash and the frame, and

thus, prevents dust, rain, and snow fromentering the interstices between said'l sash and frame.

To the above purposes, our invention consiste in certain novel features of. construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claim, and illustrated in .the acin which Figure v showing the arrangement of the window strips thereon; Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1; Fig. 3 is a horizontal section taken onthe line 3--3 of Fig. 1; Fig. 4 is a horizontal section taken approximately on the line lL-f4, or at the point where the top rail of the lower sash and lower rail of the upper sash meet, Fig.

5 is a side elevation of the central portion ofone of the strips which is positioned adjacent to the 'parting strip on the side of the window frame; Fig. 6 is a detail section of the section of weather strip which is posi- 'ing the strips tioned at the top of the window frameand against which the top rail of the upper sash engages; Fig. 7 is a detail section illustratwhich are arranged on the meeting rails of the sashes; Fig. 8 is a detail section showing the strip against which the bottom rail of the lower sash engages.

Referring by numerals to the' accompanying drawings 1 designates the sheet metal and pmvied in its Sides with the usual guideways 2, separated by the vertically disposed rbB, which forms the parting strip, and in which guide-ways operate in the usual manner theklower sash 4 and u -per sash 5. These sashes are constructed vo sheet metal, and Iformed .on the edges are the projecting flanges 6, which 'lit against the corresponding shoulders formed in the frame 1. i

7 designates the weather strip which is ositioned at thebottom of the window graine, which stri is constructed of suitable resilient inetalo inverted `L-sha e in cross section, and the horizontal portion of said .strip is arranged on top of the shoulder at the front ed e of the' lower portion of the frame. 1 wit the vertical portion of said strip projecting downwardly in osition to be engaged by the iange 6l on the ower edge of the bott-om rail of the lower sash. The

wil readily givel when. engaged by the flange 7, and, when the lower sash is closed, will frictionally en age against the face of the lower rail of t e lower sash, and thus forni a very tight joint between the lower rail ofthe lower sash and the window frame. Arranged on the rear upper corner of the top rail of the lower sash 1s an inverted U- shaped strip 8, constructed of suitable sheet metal, and arranged on the front upper corner of the lower rail of the upper sash is a correspondin U-shaped strip 9, which strips engage and t into one anotherl when the saslies are closed, thus forming a tight joint between the-meeting rails of the upper and lower sashes. g l Fixed to the under side of the top of the window frame 1 and extending transversely between the ribs 3 is a vertically disposed rib 10, to which is secured in any suitable manner an inverted U-shaped strip 11, which frame, which strip is constructed of vsuitable sheet metal and receives the flan e 6 on the front u per edge of the top rail o the upper sash, t us forming a tight joint between said top rail and the upper portion of the window frame. y

Fixed in any suitable manner to each rib 3 is a strip 12, the rear edge of the upjer half of which is bent'to forni a vertica ly disposed channel 13 which extends from `a point o posite the top rail of the lower sash upwarc y to the top of the window frame, and the front edge of the lowerjhalf of the strip 12 is bent to form a channel 14, which extends from a pointopposite the lower rail of the upper sas to the ottoni ofthe frame stri 7 being constructed of resilient metall extends between the sides of' the window' 1, and these channels receivethe eorrespond- .ing anges 6 formed on the edges of the side dei'z'achably sea-ted on said ribs, the edges of which strips are bentinto channels'to receive portions of the side rails of the sashes operating in the Window frame, and the channel on the upper half of each strip being oii'set relative to the channel on the lower half of the strip.'

In 'testimony whereof, we have signed our names to this specification, vin presence of two subscribing Witnesses.
